Figure 3From: Base excision repair of ionizing radiation-induced DNA damage in G1 and G2 cell cycle phasesIncision of oligonucleotide with 8-Oxo-G DNA lesion. The labeled oligonucleotide was incubated with cell extracts prepared from synchronized G1 or G2 HeLa cells either irradiated or not irradiated. The cleavage products on the gel were quantified with PhosphorImager to determine percentage cleavage.Back to article page
